LLVM ORC / JITLink is another similar project: JITLink handles single-file linking of MachO, ELF or COFF objects into a target process. ORC coordinates JITLink instances -- running compiles / links on demand and tracking dependencies between objects being linked on different threads.

See e.g. https://www.youtube.com/watch?v=i-inxFudrgI and earlier talks.

ORC is used by CERN's Cling c++ interpreter, Julia, PostgreSQL (for JIT database queries), the Clasp LISP VM, the LLDB debugger (for expression evaluation), and many other projects.
